MARKER FOR- conn-rnaivrnns.

Specification of Letters Patent.

Application filed Fans 29, 1915. Serial No. 37,008.

To all whom it may concern:

Be it known that 1, CriAnLns E. NORMAN, a citizen of the United States, residing at Zeal-ing, in the county of Story and State of Iowa, have invented new and useful Improvements in Markers for Corn-Planters, of which the following'is a specification.

This invention relates to markers for corn planters, and it has for its particular object to produce a marker support of simple and improved construction whereby the marker may be firmly supported for operation or in. an inactive position,as may be required.

A further object of the invention is to simplify and improve the construction of the marker support and the link members or braces whereby the support is connected with the marker bar.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings, Figure 1 is a top pla view of the rear portion of a planter frame to which the improved marker support and marker have been applied, the marker being shown in position for operation. 'Fig. 2 is a rear view of the same, showing the marker raised to an inactive position. Fig. 3 is a rear view, showing the marker in position for operation. Fig. 4 is a side view, showing the marker in an inactive position. Fig. 5 is a perspective view, showing the rear portion of the planter frame, the marker support, the braces and a portion of the marker bar. Fig. 6 is a perspective view, showing the two brace members detached and separated to illustrate the construction of the stop joint. Fig. 7 is a detail plan view of a portion of the seat showing the marker bar in section. Fig. 8 is a perspective view showing a modified construction.

Corresponding parts in the several figures are denoted by like characters of reference.

Theimproved marker support includes a sleeve 15, preferably of polygonal shape, having a fiat end wall 16 abutting on the rear cross barl'Z' of a planter frame with 1 which said sleeve is pivotally connected, as

by a bolt or other suitable pivot member 18. The sleeve 15 is provided with side walls 19 which are apertured for the pas sage of a pivot member 20 on which the marker bar 21 is mounted for pivotal movement. The sleeve 15 has a rearwardly extending arm 22 with which a. linlc or brace member 23 is connected by a rule joint 24;. The rearward end of the link 23 is connected by a brace rod 25 with the marker bar 21, the brace bar being provided with a plurality of apertures 26 for adjustable connection with the marker rod by means of a pin or bolt 27. The proximate ends of the members 23 and 25 are provided with overlapping end portions 23, 25 pivotally connected together by a pin or bolt 28, and having oifsets or shoulders 29 which, by causing the ends of the members 23 and 25 to overlap will present a neat appearance. This construction, however, is not essential, as the members 23 and 25 may be placed with their opposed faces contacting, as seen in Fig. 8, and connected together by the bolt or pivot member 28.

It will be readily seen that when the marker bar, which carries at the outer end thereof a marker 30 of conventional construction, such as a disk, as shown in the drawings, is lowered to operative position at one side of the planter, the rearward movement of the marker is limited by the rule joint 24, the opposed faces of which will contact with each other. The angular relation of the marker rod with respect to the planter frame may be varied by shifting the bolt 27 from one to another of the apertures 26. To change the marker from one side of the planter frame to another the sleeve 15 is simply turned about the axis of the bolt 18, thus permitting the marker to swing from side to side. To support the marker rod or bar and its related parts in a raised or intermediate position, said bar be temporarily connected with a seat S of the planter by a catch device 35 of appropriate construction, the rule joint serv ing to permit the marker bar to swing forwardly into engagement with such catch Patented Nov. 36 1915.

device whereby the inarker will be supportby those skilled in the art to which it appertains from the foregoing description taken in connection with the drawings hereto annexed. i

The device is simple in construction, inexpensive and easily applied to or assembled with corn planter of conventional construction. The use of ropes for bracing the marker rod is avoided, and the annoyance isv thus avoided of having to adjust such ropes as they become taut or slack owing to weather conditions.

Having thus described the invention, What is claimed as new, is

1. In a device of the class described, the combination with a planter frame, ofa sleeve pivoted thereon, said sleeve having a rearwardly extending arm, a link, a rule joint connecting the link with the arm, a marker rod pivoted in the sleeve, and a brace link. a

2. In a device of the class described, the combination with a planter frame, of a sleeve pivoted thereon, said sleeve having a rearwardly extending arm, a link, a rule joint connecting the link with the arm, a marker rod pivoted in the sleeve, and means whereby the marker rod is adjustably' connected with the link. Y

3. The combination with a planter frame, of a sleeve pivoted thereon, said sleeve'having fiat substantially parallel side walls and a rearwardly extending arm, a marker rod pivoted between the side walls of the sleeve,

i a link, a rule joint connecting the link with the rearwardly extending arm, a brace rod mastering the marker aid with as pivoted pivotally connected with the link, and means for connecting the brace rod adj ustably with the marker rod.

In testimony whereof I affix my signature 7 in presence of two witnesses.
